The human teeth are a widely available form of weapon for self-defence or destruction. This is evident in various sexual assault or abuse cases, leaving impressions that are often the only piece of evidence in investigation. Hence, there is a need for the analysis of bite impression.

Bite mark analysis can be useful in identifying the source of the impression on a victim. This can assist in suspect identification. However, there are many controversies regarding bite mark analysis as it is based on the assumption that the human dentition is unique to individual and there is no standardized method of analysis. Hence, there is a need for research in this aspect.

There are currently several techniques used in bite mark analysis, each with its own limitations. The BitePrint© software is developed in hopes of setting a gold standard analytical system for bite mark industry to ensure that bite mark evidence is as robust as any other evidence presented in court. It can analyse 2-dimensional and 3-dimensional images and is computer operated, reducing examiner’s bias and subjectivity. However, as it is a newly developed software, it has not been tested of its reliability and accuracy in measuring bite mark. This literature hope to shed light into some of the things that BitePrint© software can do, and that it will assist forensic dentists in future bite mark analysis.
